Abstract
The invention discloses multiple-unit self-cleaning filter, at least three vertical filters have been mounted side by side in the centre of a rectangle stand type support, a recovery tube connected respectively with each filter bottom liquid outlet is horizontally installed with support side, a feed pipe connected respectively with each filter bottom inlet is horizontally installed with recovery tube underlying holder, a blow-off pipe connected respectively with each filter bottom inlet is horizontally installed with the support below feed pipe, a blowoff valve is separately installed between blow-off pipe and the inlet of each filter bottom, a liquid feed valve is separately installed between the inlet and blow-off pipe of each filter bottom.The present invention is connected in parallel with multiple self-cleaning filters, and install pressure difference speed changer additional between the inlet and outlet nozzle of each filter element, it can effectively control the normal filtration of each filter element or be backwashed, have filter efficiency high, uninterrupted filtering, the advantages of reducing maintenance cost.
Description
Technical field
The present invention be it is a kind of suitable for the multiple-unit that the field such as petrochemical industry, medicine, water source and industrial circulating water uses from
Clean filter.
Background technology
Existing well strainer, although having good filtration effect, the advantages of resistance is small, be widely used in petrochemical industry,
The filtering in the fields such as medicine, water source, industrial circulating water, but because filter area is small, pollutant holding capability is small, is easily blocked by dirt, clearly
Wash work complexity, it is necessary to which carrying out dismounting to equipment could clean to filter element, influence operating efficiency.
The content of the invention
It is an object of the invention to provide one kind can effectively improve filter efficiency, not influence the multiple-unit of normal work in cleaning certainly
Clean filter.
The technical scheme is that complete in the following manner, multiple-unit self-cleaning filter, it is characterised in that：One
At least three vertical filters have been mounted side by side in the centre of individual rectangle stand type support, and one piece point is horizontally installed with support side
The recovery tube not connected with each filter bottom liquid outlet, be horizontally installed with recovery tube underlying holder one respectively with each mistake
Filter bottom liquid inlet mouth connection feed pipe, be horizontally installed with the support below feed pipe one respectively with each filter bottom
The blow-off pipe of portion's inlet connection, is separately installed with a blowoff valve between blow-off pipe and the inlet of each filter bottom,
A liquid feed valve is separately installed between the inlet and blow-off pipe of each filter bottom.One is installed in the opposite side of support
Switch board, switch board can be mounted to CPU automatic control cabinets or Pneumatic control cabinet and its corresponding control element as needed,
The inlet and outlet and sewage draining exit of each filter set up an automatic ball valve respectively, install pressure additional between total inlet and outlet nozzle of filter
Poor speed changer.
The present invention is connected in parallel with multiple self-cleaning filters, and installs pressure additional between the inlet and outlet nozzle of each filter element
Poor speed changer, it can effectively control the normal filtration of each filter element or be backwashed, there is filter efficiency height, uninterrupted mistake
Filter, reduce maintenance cost the advantages of.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；Fig. 2 is the mounting structure signal of any one filter in each filter element
Figure；Fig. 3 is the operation principle schematic diagram of the present invention.
Embodiment：
Embodiment is described in detail with reference to accompanying drawing, the present invention has been mounted side by side at least in the centre of a rectangle stand type support 1
Three vertical filters 5, a recovery tube connected respectively with each filter bottom liquid outlet 4 is horizontally installed with support side
6, a feed pipe 7 connected respectively with each filter bottom inlet 3 is horizontally installed with recovery tube underlying holder, is being supplied
A blow-off pipe 10 connected respectively with each filter bottom inlet is horizontally installed with support below liquid pipe, in blow-off pipe
A blowoff valve 9 is separately installed between the inlet of each filter bottom, inlet and blowdown in each filter bottom
A liquid feed valve 8 is separately installed between pipe.One switch board 2 can also be installed in the opposite side of support, switch board can root
According to needing to be mounted to CPU automatic control cabinets or Pneumatic control cabinet and its corresponding control element, in the inlet and outlet of each filter
And sewage draining exit sets up an automatic ball valve respectively, pressure difference speed changer is installed additional between total inlet and outlet nozzle of filter.Can be independent
The filtering and backwash of each filter are controlled, is allowed to be independent of each other, holding is uninterruptedly filtered.Its operation principle is：Just
Often during work, the imported valve of filter is opened, and blowoff valve is closed, and filter medium enters in filter head housings body from bottom, then
By being reclaimed after filter element filtering into housing internal upper part through liquid outlet, subsequent processing is returned to.Impurity in liquid is intercepted by filter core,
When the impurity of cartridge surface forms filter cake, the pressure difference of inlet and outlet is gradually risen, and when the differential reaches a set point, control system is pressed
According to programme output signal, the imported valve is closed, and sewage draining valve is opened, and the filter is backwashed, the filter
During backwash, the filter of other each filter units has been at normal operating conditions.After the Filter Back Washing, i.e.,
Blowoff valve can be closed, beats liquid feed valve, carries out normal filtration.
